REFRIGERATOR BOX.

ums]. mea novembere, 1924.' Serial no. 747,768. r

This invention is an improvement in wall construction for refrigerators, provision safes, or other analogous cabinets or containers so constructed as'to prevent the ready .5 transfer of heat through the wall.

' In my improved construction there is employed as one important feature, a, metal frame to which the outer wall is secured, and which is spaced from the inner wall or huing. Preferably this metal frame extends 1 along the angles of intersectionof the sides, 'topand bottom of the casing, the several sections being welded .or otherwise rigidly secured together at the corners. The outer .6 walls are preferabl each in the form of a single panel and al the panels-are sealed to the frame to make an air-tight construction. By means of my improved construction I avoid the usual wood frame members which inner and outer walls, and which have poor insulating properties.

. J I v Fig. 2 is a horizontal section'on the line 22of Fig. 1, the center portion ofthe box being broken away. Y a

, Fig. 3 is a perspective view of a portion of itlhe metal frame incorporated in the box wa Fig. 4is a horizontal section on the line 4d4 of Fig.5, and showing another form,

an I v Fig. 5 is avertical section onthe line 5-5 "of Fig. 4. x I

In my improved construction I employ a metal frame which is preferably formed of.- angle iron sections which are welded or otherwise rigidly secured'together at the corners of. the-box. The frame shown in Figs. 1, 2 and 3, includes four members conare used at the corners for connecting the Asa further object of my invention I elimlar frame, 'four members 11 connected together to make a lower "rectangular frame, and four vertical members 12 rigidly connect- -nected together to form. an upper rectanguing the four corners of the upper rectangular frame to the four corners of the lower frame. By the use of'angle irons the desired: rigid- 1ty and strength is secured, while at the same "time the frame is comparatively light.

The angle irons face outwardly, and in each angle ironisa wooden strip or bar 13 substa'ntially square in cross-section, and ofa transverse dimension slightly greater than the inside width of the flanges of the angle irons. I

To the frame constructed of these angle irons and :wooden bars there is secured the outer wall of the casing. This may be made of panels forming the top 14, bottomv 1,5 and side walls, 16. To prevent warping, each of these panels is preferably made up of a plurality of separate layers with the grain runmng in different directions in-the suecesslve layers. Such a multiple-ply con-' struction is not illustrated as it is notessential to the invention. The panels forming the outer casing wall are secured in place by boltsor screws 17 which extend through the bars 13 and through the flanges of the angle irons. Thus the outer casing is rigid l secured to and supported by the metal rame. As the wooden strips 13 extend out beyond the angle irons, the panels do not so i directly'enga e the angle irons. Thus they f 20 may be of any suitable construction and may be hinged to theframe 1'8'or to the front casing wall,19. r

The casing is provided with an inner wall or lining, 21 whichis preferably of sheet metal and welded alon the seams so as to form what is in efiect integral top, bottom,

side and back-walls. At the front' the top,

bottom and side walls are provided with outwardly .extending fl'a es 22 which are secured to the inner sur ace" of the frame 18.

Thus the front'f'rame serves asthe main or direct support for the inner wall or lining. 7 An opening through the door frame 18 may be made somewhat larger than the inside dimensions of the inner lining, so that the door 20 abuts against the flanges 22, as well as against the frame, and the outer surface of the wall 19, to form a tight seal.

The space between the inner and outer walls is filled with some solid inmlating material, such for instance as cork 23, and

this is packed in sufliciently tight and is of such construction as to materially aid 'in supporting the inner lining, particularly at the rear portion.

If the casing is to be used for a refrigerator, either with an ice box or with the evaperal' result may be secured by so forming the frame that the angle irons face inwardly instead of outwardly. In Figs. 4: and 5 I have shown such a construction in which the angle irons 26 face inwardly and are spaced from the panels. 27 forming the outer casing, by vstrips 28. These strips may be of thin, soft wood or of rubber,.or other packing material, which may be forced against the surface of the strip by the screws which 'connectthe panels to the metal frame. If the strips be ofwood they may be glued to the panels, but if of rubber,'they maybe pressed to form an. air-tight joint. v I

In the construction shown in Figs. 1 and 2, the lining is connected by outwardly extending flanges along all four, edges around the door opening. This is not essential as other connecting means may be employed. As shown in Figs. 4' and 5, I extend the edge portions 29 of the side walls and the lining into grooves inv the front frame member 30.

The upper and lowercdges may have vertical integral flanges 31 as indicated in dotted lines in, Fig. 5. For holding the lining firmly against the front frame 30 and aiding in directly supporting the lining, there are provided a plurality of straps 32 extending along the opposite sides and back of the lining, and terminating in outwardly extending flanges secured to therear' surface of the frame 30. Thus the lining is sealed to the front frame with an air-tight joint.

It will be noted that in my improved construction the inner lining which is preferably of metal coated with enamel or other surface-protecting compound, is-not directly connected to the main metal frame nor to the outer walls except along the narrow space surrounding the door opening. The insulation is as effective at the corners as at other parts, which is not the case with other refrigerator constructions with which. I am familiar.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:

A refrigerator box including an outer wall having a door frame, an inner lining formed of sheet metal and provided with outwardly extending flanges secured to the inner surface of said door frame, insulation between said outer wall and said lining, and a skeleton metal frame within the space between said outer wall and said lining and secured to said outer wall.
